What is the different between Diffusion and Osmosis?

Answer 1

Osmosis is the movement of a solvent (water) into a cell where the concentration of a solute is higher, the lower concentration of solute being outside the root cells. Diffusion involves the spreading of a solute from areas of higher concentrations to areas of lower concentration within a solvent.

Osmosis is made possible by a semi-permeable membrane which allows the solvent in, instead of allowing the solute out.
Diffusion is the movement of molecules or ions from high concentrated medium to low concentrated medium due to the continuous free movement of molecule , that doesn't require any membrane , simply it's like the movement of perfume molecules in room so that you can smell it everywhere in the room , Osmosis is the same as diffusion but first it has to be water second there must be a semi-permeable membrane or a selectively permeable one between mediums ...
Pretty much osmosis is the diffusion of water molecules from an area of high to low c

and diffusion is the movement of any molecule from an area of high to an area of low c

so osmosis is diffusion just the diffusion of water.
Diffusion: it is the movement of molecules from a region of high concentration to a region of low concentration

Osmosis: it is the movement of specifically water molecules from a region of high water potential to a region of low water potential through a partially permeable membrane. Osmosis is only ever the movement in LIQUID such as water, from a high concentrated area to a less concentrated (works against the gradient).

Diffusion has the same theory, but is usually with gas.

* Diffusion can happen within liquid too. It is only water that moves in osmosis.

Answer 2

Diffusion is the process in which there is movement of a substance to an area of lower concentration of that substance to an area of lower concentration whereas osmosis is the diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal.

Answer 3

Osmosis is the movement of a solvent (water) into a cell where the concentration of a solute is higher, the lower concentration of solute being outside the root cells. Diffusion involves the spreading of a solute from areas of higher concentrations to areas of lower concentration within a solvent.

Osmosis is made possible by a semi-permeable membrane which allows the solvent in, instead of allowing the solute out.

Green Shinobi(the answer above is kind of wrong, so are the others so I am going around pasting my answers one by one):

Diffusion is the movement of substance (anything- solid ,liquid, gas, etc.) from a higher concentration gradient to a lower concentration gradient.

Osmosis is the net movement of water molecules from higher concentration gradient to a lower concentration gradient through a partially permeable membrane

So the difference is that diffusion involves movement of any particles/ substance (e.g. solid, liquid, gas) while osmosis can only occur with water.

Another one is that diffusion can occur with or without a membrane but osmosis can only occur with a membrane.

Hope this helps. :)

Answer 4

Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane while Diffusion is the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration

Answer 5

diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration
